Metastatic melanoma is a serious and aggressive form of skin cancer that occurs when melanoma cells spread from the primary tumour to other parts of the body, including distant lymph nodes. When metastasis involves the mediastinal lymph nodes, it poses a significant clinical challenge, as early detection and accurate diagnosis are crucial for effective treatment planning.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS -TBNA) is an invaluable diagnostic tool in the assessment of mediastinal nodal metastases in cases of metastatic melanoma. EBUS - TBNA is a minimally invasive procedure that allows clinicians to sample and examine lymph nodes and adjacent structures within the mediastinum using a bronchoscope equipped with an ultrasound probe and fine-needle aspiration capability.

Diagnosing metastatic melanoma with EBUS -TBNA involves the following steps:
Localization: The bronchoscope is advanced into the airways, and the ultrasound probe helps identify suspicious lymph nodes in the mediastinum. These lymph nodes are often enlarged due to metastatic melanoma.
Needle aspiration: A thin, flexible needle is guided through the bronchoscope to puncture the targeted lymph node. This needle collects tissue samples for biopsy.

Pathological evaluation: The collected tissue samples are sent to a pathology laboratory, where they are examined under a microscope by a pathologist. The presence of melanoma cells in the lymph node confirms the diagnosis of mediastinal nodal metastases.
Diagnosing metastatic melanoma with EBUS-TBNA offers several advantages, including its minimally invasive nature, high diagnostic accuracy, and the ability to provide rapid results. This information is crucial for staging the cancer, determining the extent of metastasis, and guiding treatment decisions.
